On the large-Q2 behavior of the pion transition form factor

open access: yesPhysics Letters B, 2017
We study the transition of non-perturbative to perturbative QCD in situations with possible violations of scaling limits. To this end we consider the singly- and doubly-virtual pion transition form factor π0→γγ at all momentum scales of symmetric and ...

An intelligent Adaptive Neuro-Fuzzy Inference System to Estimate the Behavior factor of EBF steel frames under Pulse-type Near-fault Earthquakes [PDF]

open access: yesمهندسی عمران شریف, 2021
One of the most important effective parameters in earthquake, is behavior factor, which is depends on various factors such as structural geometric properties, structure ductility (performance level), fundamental period of the structure, damping, soil ...

Seismic Vulnerability Evaluation of a Historical Masonry Tower: Comparison between Different Approaches

open access: yesApplied Sciences, 2022
Throughout the last few decades, the scientific community has paid great attention to the structural safety of historical masonry constructions, which have high vulnerability with respect to seismic activities. Masonry towers are very widespread in Italy

Investigation of Subpanel Size Effect on Behavior Factor of Stiffened Steel Plate Shear Wall [PDF]

open access: yesJournal of Structural and Construction Engineering, 2019
Steel plate shear wall (SPSW) systems have been used in recent years in highly seismic areas to resist lateral loads. In general, a steel plate shear wall system consists of a steel plate wall, boundary columns, horizental floor beams and optional ...

Investigation the behavior and ductility of low rise RC tunnel –form systems [PDF]

open access: yesمجله مدل سازی در مهندسی, 2018
The tunnel form buildings provide some advantages for medium to high-rise buildings that constructed by using a special tunnel form technique are commonly built in countries facing a substantial seismic risk. There are no special requirements for seismic

Optimized Analysis and Design of the link Beam With Eccentrically Braced Frame [PDF]

open access: yesمجله مدل سازی در مهندسی, 2010
Eccentrically braced frames have high stiffness and suitable energy damping against the lateral forces like the earthquake. In this bracing system, the required stiffness and formability of the frame is provided by the link beam, and are dependent on the

Behavioral Factors of Longevity [PDF]

open access: yesJournal of Aging Research, 2011
The majority of studies on longevity have focused disproportionally on biomedical aspects of longevity [1]. While biomedical aspects undoubtedly play an important role in determining the length and quality of life, there are also a number of important social, psychological, and behavioral factors associated with longevity.
